United States Patent Of'fice 3,124,379 ANTI-RATTLING HOOK Allen E.Lorch, 5120 Lincoln Ave, Los Angeles, Calif. Filed Oct. 3, 1961, Ser.No. 142,670 1 Claim. (Cl. 292F114) This invention relates toimprovements in hooks usable to maintain doors and other closure membersin their closed positions and more particularly to a spring loaded hookof an anti-rattling character.

Among the objects of the invention are: to provide a hook that will moresafely maintain itself in its operative position, and to provide animproved means to hold in operative position the spring with which thehook is loaded.

The invention includes, as a new article of manufacture, a novel clipapplicable to a conventional hook to hold in place on said hook a springwhich yieldingly holds the hook in an extended position.

Other objects, advantages and features of invention will hereinafterappear.

Referring to the accompanying drawing, illustrative of a preferredembodiment of the invention,

FIG. 1 is a side elevation of the device, the extended position of thehook proper being indicated by a dotted line.

FIG. 2 is a top plan view of the device.

FIG. 3 is an end elevation looking at the left end of FIG. 1.

FIG. 4 is a vertical section on line 4-4 of FIG. 2, parts being brokenoff to contract the view.

FIG. 5 is an extended view of the spring holding clip as it appearsbefore the final bending operation.

Referring in detail to the drawing, the hook proper 5 together with itsshank 6 and eyeletted portion 7 is formed from a single rod which iscircularly bent at one end to provide the eye 8 with which cooperatesthe eyebolt or screw 9 or other fastener to which the hook is anchored.

A clip formed of a strip of form retaining sheet material, desirablysheet metal, is mounted upon the hook and forms a partial housing forits eyeletted portion 7 and the adjacent portion of the hooks shank.Said strip is right angularly bent toward the same end at two spacedapart lines 15a and 15b in its mid-length portion to provide across-wall 16 which has a central aperture 16a (see FIG. 5) throughwhich the hooks shank is slightly slidable.

A compression spring 17 is loosely coiled around the hooks shank withone of its ends abutting said crosswall and its opposite end abutting atleast one of the two shoulders 7a and 7b resulting from circularlylooping the eyeletted part of the hooks shank. As a result the hookproper is normally retracted by the spring to the full line position ofFIG. 1, but it can be extended 3,124,379 Patented Mar. 10, 1964 to thedotted line position of FIG. 1 against the opposition of the spring whennecessary.

It is to be observed that the thickness of the eyeletted part 9a of thescrew 9, which occupies the eye 8 is considerably less than the diameterof that eye, thus permitting the amount of tolerance or spring opposedplay indicated by the double headed arrow 25 in FIG. 4.

Viewing the clip 15 in its extended condition, shown in FIG. 5, each endportion thereof is circularly enlarged as indicated at 29, around eachof the apertures 27. The eyeletted part 9a of the screw 9 extendsthrough said apertures 27 when the clip is in its mounted position.

This device not only prevents doors from rattling in the wind, but alsofacilitates mounting in its operative position the spring loaded hook,for it provides a spring opposed tolerance which takes care ofinexactness in positioning the eyeletted screw 9 and the eyeletted screw(not shown) carried by a door or other closure.

In assembling, after the clip has been bent into its final form and thespring 17 has been put into place by threading it over the hook proper,the clip 15 is threaded over the hook proper by means of its aperture16a, and its cross-wall 16 is abutted against the spring. Then theeyelet portion of the screw 9 is crirnped down from an open conditionafter having been inserted through the alined eyes 8 and 27.

I am aware that it is not broadly new to provide extensible, springloaded hooks, but this invention relates to the improvement upon suchstructures defined by the claim which follows.

I claim:

A device of the kind comprising a hook provided with a shank consistingof a rod circularly looped at one end, thus providing an eye, a clip ofform retaining sheet material mounted upon said shank and forming apartial sleeve therearound, said clip having oppositely disposed spacedapart eyeletted portions at one end and having at its opposite end across-wall with an opening through it through which the shank of thehook is slidable, a fastening member for the hook having an annular endportion extending through both the eyeletted end portions of said clipand through the eyelet of said rod, and a compression spring looselycoiled around said rod under compression, one end of said springabutting said cross-wall and the opposite end thereof abutting theeyeletted end portion of said rod, the part of said fastener whichpassses through the eye of said rod occupying only a part of thediameter of that eye, thus allowing a limited longitudinal movement ofsaid rod in opposition to said spring.
